Strategy & Solution ⬇
Step 1: Fill in numbers that tell you the answer already.
Step 2: Keep in mind that you can only have 1 of each number in a row or column.
Step 3: Look at the hints (the tiny numbers in the top left of the cages) you can just have a skim around of what you will be working out.
Step 4: I started off by looking at smaller cages equations to make it easier to start off.
Step 5: As I was typing some numbers in the cages I kept on making sure that there weren't any multiples of numbers in a row or column.
Step 6: This task is also all about guess and check because if you place a number and notice that there is another possible number you have to wait to find out more numbers to then be sure what number goes there.
Step 7: Midway through the Mathdoku I regularly checked that they all added up correctly and that there were no mistakes.
Step 8: After I checked all the numbers at the end when I think I was finished I clicked submit after lots of guessing and checking.
Step 9: Once you have followed these steps you can change the difficulty level on the Mathdoku so you can challenge yourself more!
